[SOLVED] Error: Kernel failed: invalid device pointer (17) at lline 99

[2bForgotten]

Hi @Alex Pasumansky,

When trying to refine a mesh, I keep running into this error: Kernel failed: invalid device pointer (17) at line 99.

As I suspected it could have to do with the Nvidia drivers for the two RTX 2080 cards in the workstation, I tried both
- Studio driver v472.12
- Game ready driver v496.13
Both to no avail.

Also tried to run with only 1 RTX 2080. All in vain.

Machine is Windows 10, dual Xeon E5-2678 v3 @2.50 GHz, 128 GB RAM.
Agisoft version is 1.7.5 build 13229 64bit

Please inform me how to solve this error.

***EDIT [SOLVED]***
Although I searched this forum before posting, I must have overlooked this post that solved the issue by switching to OpenGL.

Hello 2bForgotten,

Looks like you are observing the similar problem as reported before:

The identical CUDA cards cause the problem for Refine Mesh operation. As a current workaround you can switch to OpenCL implementation by setting main/gpu_enable_cuda tweak to False value.
